Trilobites


Trilobites are a group of extinct arthropods (similar to crustaceans) with a hard shell. They are common in Devonian rocks in the Virginia / West Virginia area. Usually, almost all are partial trilobite molts. Occasionally whole ones are found. The most common trilobite is the Eldredgeops (Phacops) Trilobite.


Eldredgeops Trilobites


This is a complete Eldredgeops (Phacops) Trilobite from the Fossil Site.

It flaked right out of the matrix when found. Luckily it didn't break. From the Needmore Formation of WV.



This is an enrolled Eldredgeops (Phacops) Trilobite from the Lost River Site.
It's a little smashed, one eye is visible. From the Needmore Formation.



As with most fossil sites, the Trilobites found here usually look like this: Partials and Molts.




Brachiopod Fossils



Brachiopods look like little clams, however, they are actually very different.
Brachiopods are one of the most abundant fossils in the Needmore Formation and other Devonian formations in the area.
Some Brachiopods are still alive today, but Pelecypods (clams and such) far outnumber them.
There are many different types of Brachiopods. Many look nearly identical. Below is one of the more common ones that can be found.



Rhipidomella sp.


This is a fairly common brachiopod that can be found at the site. Like the other fossils, they are very fragile.



Coral Fossils



Coral pieces are abundant in the Needmore Formation. A few different types are shown below.



Trachypora sp.


This is a Trachypora coral. It's a colony of branching coral.
This type of coral is spread out over the rocks at this site. "runners" that stretch for at least foot can be found throughout the rocks.

When found, specimens are encrusted with a thin layer of shale, and need dissolved in a very weak solution of acid to reveal the actual blue/grey coral (shown here).
Also, specimens are usually broken into numerous pieces, this one is glued together back into its original shape.



This is a type of solitary coral that is found throught the Needmore Formation. They are usually smaller than the one imaged here. This coral is also common in the Mahantango formation which is also found nearby.

This is a great updated fossil sites book with at least one fossil site in each state. Each site is broken into 2 pages. One has detailed information, such as directions, GPS coordinates, formation information, etc... The other is dedicated to images of the site and the fossils found there. It also gives information on fossil 'viewing' sites such as dinosaur trackways, museums, and active excavations.
Plus, my fossil photos are peppered throughout this book!
